A medical student (Steve Sandvoss) is working on a research project and discovers that he is able to reanimate recently-deceased mice. He takes a break from his work to go on a trip with three friends. He admits to his friend Sophia (Nicole Vicius) that he loves her – but shortly after this she falls into a nearby lake and drowns. Using the methods from his research project he is able to revive her, but the process requires that he extract the hormone Oxytocin from a recently-dead corpse.
